I’d wanted to hike to Rockbound Lake in Banff National Park for some time despite the fact it’s one of the ‘don’t do’ hikes in the book Don’t Waste Your Time in the Canadian Rockies. The author actually suggests “it helps to wear colourful boot laces so you’ll have something interesting to look at.
But when it’s late October and you still have the itch to hike in the mountains, where do you go from Calgary, especially if it’s a windy day? The Rockbound Lake trail turned out to be a great choice.

The first 5 km on the Rockbound Lake hike
I would agree that the first 5 km on the hike to Rockbound Lake isn’t very interesting. It’s steep (you gain 518 m) with occasional peek-a-boo views but not much else.
We did see a couple of ptarmigans – perhaps one of the stupidest birds out there as you almost step on them before they take off. However, they did provide a welcome distraction.
And then in short order we were into snow so everything seemed prettier.
Hiking the backside of Castle Mountain
When you finally reach the meadows, the landscape gets your attention as the backside of iconic Castle Mountain slowly comes into view. (Everyone who drives the highway between Banff and Lake Louise has admired Castle Mountain at some point but few have ever see its backside.)
Large boulders, scattered larch, a couple of streams, and some lovely distant mountain views also show up. You certainly don’t need colourful boot laces here.
The hike up to to Rockbound Lake
Count on about 45 minutes of easy hiking from the time you break out of the woods to reach Tower Lake. It was already frozen when we visited in October but reportedly it’s a pea-green colour.
From Tower Lake cross a footbridge over the outlet stream. This is the one place on the hike, except at the beginning of the trail, that you’ll see any signage pointing to Rockbound Lake.
Next there’s about 10 minutes of steep hiking up the headwall to reach the high point of the Rockbound Lake hike at 2,210 m.
From there it’s an easy walk through larch forest to reach Rockbound Lake. If there is snow on the trail, take gaiters. If we’d had to break trail we would have been up to our knees in snow. The same thing will happen to you if you step off the trail.
I think Rockbound Lake makes a great destination for a fall hike especially on a windy day as you’re largely protected. Another great time to do the Rockbound Lake hike would be in mid-September when the larch trees start to turn yellow.
Where to stay near the Rockbound Lake trailhead
The trailhead for the Rockbound Lake hike is close to Castle Junction and Lake Louise.
There are no backcountry campsites on the Rockbound Lake hike but there is the nearby Johnston Canyon Campground that is open from May 25 – September 24th. Reserve a campsite online.
